GB/T 19725.2-2020 Agricultural and forestry machinery—Safety requirements and testing for portable,hand-held,powered brush-cutters and grass-trimmers—Part 2:Machines for use with back-pack power unit
Abstract
This part of GB/T 19725 specifies the safety requirements and test methods for portable backpack power brushcutters and lawn mowers driven by internal combustion engines and transmitting mechanical power to cutting attachments. It proposes methods to eliminate or reduce various hazards caused by the use of the whole machine, and stipulates the requirements for safety operation-related information provided by manufacturers.
This part and the relevant chapters of Part 1 (see 4.1) cover all serious hazards, dangerous situations, and serious harm events related to the whole machine during normal use and reasonable misuse of the whole machine that can be foreseen by manufacturers, except for the whole-body vibration hazards caused by backpack power units.
Note 1: There are currently no standard test procedures for measuring whole-body vibration caused by backpack power units.
Note 2: For a list of serious hazards, please refer to Appendix A and Appendix C of GB/T 19725.1—2020.
This part applies to products manufactured after its implementation.
This part does not apply to machines equipped with non-integral metal blade structures, such as chain-driven or knife-driven blades.
